Transient tachypnea - newborn

Definition

Transient tachypnea is a breathing disorder seen shortly after delivery in early term or late preterm babies.

Causes

As the baby grows in the womb, the lungs make a special fluid. This fluid fills the baby's lungs and helps them grow. When the baby is born at term, chemicals released during labor tell the lungs to stop making this special fluid. The baby's lungs start removing or reabsorbing it.

The first few breaths a baby takes after delivery fill the lungs with air and help to clear most of the remaining lung fluid.

Leftover fluid in the lungs causes the baby to breathe rapidly. It is harder for the small air sacs of the lungs to stay open.

Transient tachypnea is more likely to occur in babies who were:

Symptoms

Newborns with transient tachypnea have breathing problems soon after birth, most often within 1 to 2 hours.

Symptoms include:

Exams and Tests

The mother's pregnancy and labor history are important to make the diagnosis.

Tests performed on the baby may include:

The diagnosis of transient tachypnea is most often made after the baby is monitored for 1 or 2 days. If the condition goes away in that time, it is considered to be transient.

Treatment

Your baby will be given oxygen to keep the blood oxygen level stable. Your baby will often need the most oxygen within a few hours after birth. The baby's oxygen needs will begin to decrease after that. Most infants with transient tachypnea improve in less than 12 to 24 hours, but some will need help for a few days.

Very rapid breathing usually means a baby is unable to eat. Fluids and nutrients will be given through a vein until your baby improves. Your baby may also receive antibiotics until the health care provider is sure there is no infection. Rarely, babies with transient tachypnea will need help with breathing or feeding a week or more.

Outlook (Prognosis)

The condition most often goes away within 24 to 48 hours after delivery. In most cases, babies who have had transient tachypnea have no further problems from the condition. They will not need special care or follow-up other than their routine checkups.

Late preterm or early term babies (born about 2 to 6 weeks before their due date) who have been delivered by C-section without labor may be at risk for a more severe form known as "malignant TTN."
